AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
641 PM CDT MON APR 26 2010
.AVIATION...
GREATEST CONCERN FOR THIS TAF ISSUANCE IS THE ONGOING CONVECTION
ACROSS CENTRAL TEXAS WHICH MAY AFFECT OUR NORTHERN
SITES...PARTICULARLY CLL...THIS EVENING. FAIRLY CONFIDENT THAT
THUNDERSTORMS SHOULD START TO WEAKEN SHORTLY AS DAYTIME HEATING IS
LOST AND STORMS MOVE INTO SLIGHTLY LESS FAVORABLE ENVIRONMENT OVER
SOUTHEAST TEXAS. AT THIS TIME IT DOES NOT APPEAR THAT THIS
ACTIVITY WILL AFFECT THE METRO TAF SITES.
FRONTAL BOUNDARY OVER CENTRAL TEXAS WILL MOVE INTO THE REGION LATE
THIS EVENING AND REACH THE HOUSTON AREA AROUND MIDNIGHT TONIGHT.
NORTHERLY FLOW WILL PERSIST IN THE WAKE OF THE FRONT THROUGH THE
REST OF THE TAF PERIOD WITH A FEW SCATTERED CLOUDS POSSIBLE
THROUGH MID MORNING TUESDAY. 38

.PREV DISCUSSION... /ISSUED 311 PM CDT MON APR 26 2010/
DISCUSSION...
A SHORTWAVE TROUGH ALOFT WILL PUSH ACROSS THE SOUTHERN PLAINS AS A
COLD FRONT MOVES ACROSS SE TX TONIGHT. HIGH PRESSURE AT THE
SURFACE AND AN UPPER LEVEL RIDGE WILL THEN MOVE OVER THE AREA
THROUGH THE MID WEEK PERIOD. A STRONG UPPER LEVEL STORM SYSTEM
OVER THE ROCKIES WILL THEN MOVE INTO THE PLAINS DURING THE LATTER
HALF OF THE WEEK AND EARLY NEXT WEEK.
THE COLD FRONT DROPPING SOUTHWARD WILL BRING A SLIGHT CHANCE OF
RAIN OVER THE NORTHERN COUNTIES TONIGHT. THE MODEL SOUNDINGS
INDICATE THAT THERE IS A SLIGHT CHANCE FOR A STRONG STORM.
OTHERWISE...THE MODELS INDICATE THE NEXT CHANCE OF RAIN WILL BE
LATE THURSDAY WHEN ONSHORE WINDS WILL BRING GOOD WARM AIR AND
MOISTURE ADVECTION TO SE TX. FORECAST MODEL SOUNDINGS INDICATE A
DECENT CAP WILL BE IN PLACE OVERHEAD. HOWEVER...GIVEN THE STRENGTH
OF THE MOISTURE ADVECTION COULD NOT RULE OUT AT LEAST A SLIGHT
CHANCE FOR SHOWERS. COULD NOT RULE OUT THUNDER ON FRIDAY GIVEN THE
INSTABILITY FORECASTED.

AVIATION...
COLD FRONT ACROSS NORTH TX WILL PUSH SLOWLY ACROSS SE TX THIS
EVENING. GFS BUFR SOUNDINGS SUPPORT THE POTENTIAL FOR ISOLATED
HIGH-BASED STRONG CONVECTION TO DEVELOP NEAR THE FRONT MAINLY NORTH
OF KCXO. THE PRIMARY TIME FRAME FOR CONVECTIVE DEVELOPMENT IS
EXPECTED TO BE 00-04Z. SINCE COVERAGE IS EXPECTED TO REMAIN VERY
ISOLATED HAVE PLACED ONLY CBS IN THE KCLL...KUTS...KCXO TAFS. LEFT
CBS OUT FURTHER SOUTH WHERE CONFIDENCE IS LOWER. OTHERWISE...VFR
CONDITIONS EXPECTED THROUGH THE FORECAST PERIOD. SOUTHWEST WINDS
AROUND 10 KTS WILL BECOME MORE SOUTHERLY LATE AFTN IN HOUSTON
TERMINALS AS A WEAK SEABREEZE PUSHES INLAND. WINDS WILL SHIFT TO
THE NORTH 06-09Z WITH PASSAGE OF FRONT. SCATTERED HIGH-BASED CU

A WEAK COLD FRONT ACROSS NORTH TX WILL PUSH ACROSS THE BAYS AND
COASTAL WATERS LATE TONIGHT. WINDS WILL SHIFT TO THE NORTH AFTER
THE FROPA. WILL HAVE A BRIEF SCEC FOR THE 00-60 NM WATERS FROM

WILL QUICKLY RETURN TUE NIGHT/WEDNESDAY AS THE SFC HIGH MOVES OFF
TO THE EAST. THE PRESSURE GRADIENT WILL TIGHTEN THURSDAY/FRIDAY AS
SFC LOW PRESSURE DEVELOPS ALONG THE LEE OF THE ROCKIES. THIS WILL
RESULT IN AN INCREASE IN WIND SPEEDS TO 15-25 KTS THIS PERIOD. THE
LONG FETCH OF SOUTHEAST WINDS WILL RESULT IN HIGH SWELLS OF 7 TO
11 FEET. SCA CONDITIONS EXPECTED OVER THE 00-60 NM WATERS AND SCEC
CONDITIONS OVER THE BAYS BEGINNING THURSDAY MORNING. LITTLE
